What to Expect From Our Design-Build Process
1. Designer Interview
The project developer and an interior designer meet with you virtually to discuss what you envision for the space. We also touch on your aesthetic preferences and encourage you to create inspiration boards using sites like Pinterest and Houzz.
2. Project Estimates & Design Agreement
Based on the information gathered during the designer interview, the designer produces a design proposal, estimated lead times, and initial cost estimates. The designer then passes this information to the project developer, who compiles a design agreement.
At this point, we request a pricing services payment so we can compile a detailed and accurate cost estimate, price breakdown, and written scope of the work. Once we complete these pricing services later in the design process, we will provide a fixed-cost agreement so you know exactly what your total investment will be before construction begins. If you move forward with us, we will apply your pricing services payment to construction costs.
3. Schematic Design
The schematic design phase is about changing the form and function of your space so it works better for you. First, we measure and document your existing space. While on-site, we discuss your functional goals and determine how you want the space to feel. We also help you select layouts and products for your remodel.
4. Design Development
During this phase, we focus on your aesthetic desires, developing a specification list of all the fixtures and finishes you want. By gaining a deeper understanding of your preferences and goals, we can pin down every last detail of your project, from bathroom tile and closet dimensions to doorknobs and cabinet hardware. This is the lengthiest phase of the design process and may also include visiting showrooms and viewing samples to help you make the best selections.
5. Conceptual & Construction Drawings
Our designer uses computer-aided design (CAD) software to produce detailed conceptual drawings and 3D walkthroughs to help you visualize the finished product. We also present construction drawings to the production team and city permitting offices to ensure every last detail is accounted for.
6. Project Management & Construction
Your designated project manager prices, plans, and coordinates everything before construction begins. We work closely with you when creating the schedule to make sure it works for you. Upon signing the construction agreement, work can begin! Expect your project manager to maintain consistent and effective communication from start to finish via weekly meetings. We promise to address all issues and concerns promptly.
As construction begins, our team seals off work areas to prevent dust and debris from leaving the construction zone. We also clean up after ourselves at the end of each workday to maximize cleanliness and safety.
7. Installation & Walk-Through
Once construction is complete, the designer returns to install the finishing touches. If we helped you source new furniture, this is when we coordinate bringing those pieces into your home. If you’re using your existing furniture, the designer arranges the room to meet your needs.
During the final walkthrough, you’ll receive a certificate for Better Builders’ five-year craftsmanship warranty. Our job isn’t complete until you’re in love with how we brought your space to life!

Home Addition FAQs
If you're looking to increase your home's value and are prepared to invest the time and money it requires, you should definitely opt for a home addition. According to the National Association of Realtors, each 1,000 square feet added to a home increases its sales price by at least 30%.
Because adding a half or full bath can increase a home's overall value and sales appeal, a home addition is an investment well worth considering. Most importantly, a room addition is the best way to create a living space that's uniquely your own, adding to your personal and emotional well-being.
Experts agree the additions that add the most value to a home include kitchen, bathroom, and master suite improvements. Adding a mid-range master suite gives you a roughly 57% value on return. Some homeowners prefer to add a shed roof dormer to create an attic master suite, an addition that can return as much as 80% of its value.
A kitchen addition returns anywhere from 60% to 80% value, as do bathroom additions. Best of all, because these two rooms are highly functional and extremely practical, you not only get a nice return on your investment but enjoy a tremendous amount of use-value from them as well.
Bump-outs are similar to additions but offer a more affordable way to add living space to your Seattle home. Smaller than a full addition, they're often used to add additional square footage to an existing room, such as the bathroom, kitchen, family room, or master bedroom. There are no standard rules about what makes a bump-out, but common features include minimal exterior changes, cantilevers, lean-to roofs, and no additional HVAC services.
